Tiger is Fievel Mousekewitz's best friend and is one of the only friendly cats from the An American Tail series (the only other one being Miss Kitty). He was originally a villainous member of the Mott Street Maulers until he felt sorry for Fievel and deciding to free him and quit the group. He is voiced in every appearance by the late Dom DeLuise, with the exception to the An American Tail: A Musical Adventure with Fievel and Friends where he was voiced by Donny Gerrard (who also voiced Papa Mousekewitz on the CD).
